A study examined how well children could discriminate matches from nonmatches of multicomponent stimuli within the prototypic mental rotation task and how long it would take them to make such discriminations. The goal was to determine whether children are differentially sensitive to the various spatial features of visual stimuli and whether…

People presume that the light source in pictures comes from above, and there is some evidence that this phenomenon also demonstrates lateral biases. When investigators present multiple ambiguous stimuli or visually complex objects, people assume that the source of light is from above, and to the left. However, when single relatively simple stimuli…

Examines the effect of perspective and color on the ability of 192 secondary school children in England to observe danger points in a typical kitchen scene. Reports that more able children perform significantly better than their peers, and that the type of color employed contributes significantly to the scores but gender does not. (GEA)

This report documents a computer-based gaming system for assessing recognition performance (RECOG). The game management system is programmed in a modular manner to: instruct the student on how to play the game, retrieve and display individual images, keep track of how well individuals play and provide them feedback, and link these components by…

The relationship between creativity and perception was examined in two studies that correlated a combined total of 11 tests of perception (e.g., figure-ground and physiognomy) and creativity (e.g., remote associates and figure preferences). Four of the tests dealt with perception, five with creativity, and two with both. Since several of the tests…

Neurologically normal individuals exhibit strong leftward response biases during free-viewing perceptual judgments of brightness, quantity, and size. When participants view two mirror-reversed objects and they are forced to choose which object appears darker, more numerous, or larger, the stimulus with the relevant feature on the left side is…

Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain. (RC)

Results of four related studies revealed (1) a trend toward better differentiation of the color attribute from four years through college-age; and (2) a possible stage of development, occurring before children can organize stimulus values conceptually or multidimensionally, in which they are able to organize or "dimensionalize" stimulus values…

Skilled readers read passages while their eye movements were monitored. Certain critical words were changed by the computer as the eye was in motion. Subsequent data indicated how wide the area is from which a reader acquires information during a fixation in silent reading. (Author/BJG)

Pioneering research has shown that infants are capable of perceptual discrimination and has provided some indication of the nature of the discrimination; that is, what stimuli are differentiable. Studies have demonstrated that significant effects exist, in stimulus-pair comparisons, for age of infant, speed of movement of stimulus during…

The defining attributes of analytic ability as they relate to theoretical cognitive styles were explored in a study using a sample of 492 males aged 16-21 years. The Group Embedded Figures Test (GEFT--Witkin, Oltman, Rasher, and Karp) was used to measure field dependent and independent aptitude. Scores on the GEFT were compared with scores on an…

Spatial and temporal matching abilities of normal and disabled readers were investigated. Average and dyseidetic readers were better able than dysphonetic and alexic readers to match purely temporal information. Dysphonetic and alexic readers demonstrated greater difficulty with temporal rather than spatial information. The existence of memory and…
